Newer versions of Visual Studio are installed without a makefile for the MFC library.
As I want to change some inner parts of MFC I need to compile the library.
...but without a makefile (or solution file) this is not possible.

Anybody out there which has got a working makefile for newer Visual Studios?

Note that I have not used MFC since ~2013 but I can tell you that you can simply copy the MAK files from the VS2008 installation folder into your VS2010-VS2012 source folder and make a few changes. I have never attempted for VS2013 and above.

I believe the last version that supported recompile of the MFC framework was VC2008 with 'nmake /f atlmfc.mak MFC' from commandline. Beginning with version MSVC2010 the MAK files were removed and recompile of the library became completely unsupported.

It is possible to get the name of logged in users from a service (you have already asked that and got an answer). Using that you can guess the the user directory path and verify it by checking if the pathe exists.

But a service should not modify user data and usually does not need to read user data.

You have not told us why you need access to user directories. Maybe there is a better solution for your problem.

Just a guess, since I never did it yet:
- enumerate currently logged i user using NetUserEnum or/and NetWkstaUserEnum functions to get the SID for every user;
- use these SIDs to get info for every user from registry (HKEY_USERS\<sid>\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders)
- ...

Hope, it helps (at least to move you in some potentially useful direction).

No, it is most definitely NOT undefined behavior. This is exactly the behavior one should expect. The variable a has the binary value of -26 decimal, or 0xFFFFFFE6 in 32-bit hexadecimal. When it is passed to printf with a %d format specifier it will be interpreted as a signed decimal value and -26 is printed. There is nothing undefined about that. It is interpreting the variable exactly as the format specifier is defined to. It may not be what you want but it is as expected.

Introduction to the data:
NOAA's National Centers for Environmental Information collects global climate data and aggregates this data to provide information on climate trends and variability. One product they offer is a monthly regional analysis. The following table gives "anomaly" data by continent for January 2017. "Anomaly" means the value is the temperature difference from the average temperature from years 1910–2000.

Assignment task:
Your task is to develop an algorithm that would sort data such as these from least to greatest. Specifically, given an unsorted set of N decimal values, your algorithm should sort them to give an answer of the sorted data. For this set of N = 6, your algorithm should produce:

-0.12
0.53
0.98
1.36
1.92
3.18

Execute your algorithm for a different set of data, such as a subset of the given data, data you make up, or another month's climate data, such as February 2017: https://www.ncdc.noaa.gov/sotc/global-regions/201702

Does your algorithm work for any N? Have you thought of corner cases it might need to handle, such as N = 0 or N = 1?

If the code actually runs it is only because of the way that the compiler lays down the stack and/or what the exact code did just before the first method was called.

In the method the pointer is considered to be non-initialized but because it is a pointer that was created on the stack it will have a value, whatever was in the memory that the stack is using at that point. Thus correctly stated 'garbage'.

I am trying to make a global 2D array using vectors, but I am having some trouble in doing so. Below code is a small part of my project where I need to make a global 2D array whose size has to be passed through a command line. I am passing row and column as command line arguments.

You declare your vector as a global, but the values of row and col will be zero when it is created. Make it a local variable and let your ESSolver object manage it. Or better still make it a member of the ESSolver class.

The array needs to be dynamically allocated. This is done using the new operator. I usually prepend an "m_" to member variable names so I know that is what they are. The array will be allocated in the class constructor and released in the destructor.

Did you pass a valid line number to it like 0? If you pass it -1 "the return value is the number of unselected characters in the lines that contain selected characters" according to the documentation.

You will have to do the length limiting of each line yourself because LimitText and SetLimitText define how many total characters the control can accept, not just on one line.

Also, to get the number of pixels per character you should call GetTextExtent which is a member of the CDC class. The typical way is to generate a string with all upper and lower case letters, call GetTextExtent with that string, and then divide the resulting width by the string length to get an average for each character. There are lots of examples that show how to do this.

mycsize.cx represents the number of pixels per character originally I multiplied by 8 figuring 8 characters per line but I ended up multiplying by 10 to get 8 characters to fit
asidgprs and asidacess are 2 multiline edit controls in the Dialog
I ended doing a lot tweeking wit this to get it to the right size

Is there a reason you need to use multi-line edit controls of a fixed width? It seems like an array of single line edit controls might do what you need and it is easier to limit the length of data in them.
